I've noticed that if I have my cell phone with me and have WiFi on the IA range drops drastically (I'll need to be almost leaning against the door for the IA to open the door(s)). The bi-directional remote for the remote start hasn't helped much either.
Is this happening with both keys?

Coincidence. The IA system works by noticing changes in electromagnetic density. It's not that the system doesn't recognize the remote being close, it's that it's not recognizing his hand being in the handle. The field for that sensor is very narrow and wouldn't be affected by your cellphone at all.

Awesome, thank you copernicium. Wonder why the dealer couldn't find this themsevles? They sure do love their TSBs. Now if only i could convince them to fix the automatic rainshield wiper from not dryswiping and turning off for 15 seconds when it's raining...

Lol Electromagnetic density... Wonder if I should rub a ballon on my head before unlocking the car. I did put new batteries in the remotes and still the same issue. Although I must say it did unlock for me tonight when I went out . I wonder if humidity can affect it at all?

Rke op has noting to do with IA op. problems ive noticed. if the car is very dirty the sensor doesnt like to work. also if its below say -10 c w.e that may be in f -45 or something. they dont operate very well. ive had a few escapes come in for this issue but no focus' yet. also i found sliding your hand down the handle towards the back of the car works. btw if the lock works and the inside sensor doesnt. something is wrong in the sensor. a bcm update probably will not correct it. theres a pinpoint test to do all this shit to. so the dealer should get to the bottom. i suggest bringing a service writer out side and get them to try to open the car the same way.

I have had the same problem. Seems to be only when the car is wet and covered in road grime and salt. I found once I wash it and it dries I have no problems again. I don't remember any problems last winter though.
